KARPEN & BROS, OF CHICAGO, ILLINOIS,A CORPORATION OF WEST VIRGINIA MATTRESS AND MATTRESS MANUFACTUREApplication filed March 23, 1931. Serial No. 524,717.

This invention relates particularly to mattresses and the manufacturethereof; and the primary object is to provide for improved tufting ofmattresses.

The invention is illustrated in the accompanying drawing, in which- Fig.1 is a broken plan view of a mattress constructed in accordance with theinvention; Fig. 2, a broken sectionalview taken as indicated at line 2of Fig. l; and Fig. .3, a fragmentary view of the casingtop emp I Theinvention is shown applied to a mattress having a filling whichcomprises a body of springs and layers of cotton or the like coveringthe springs. However, the invention may be used in connection withmattresses having any suitable filling.

In the illustration given, A designates a filling comprising aspring-structure A and layers of cotton, or the like, A over thespring-structure; and B designates a casing comprising a quilted borderB and easingtops, or covers, B

The spring-structure A shown is of the type in which coil springs areencased in fabric-cells and are connected by ties 1, if

desired.

The top, and bottom fabrics B which cover the broad sides of themattress are connected with the boxing, or border, 13 by means ofcorner-seams 2.

The fabrics B are provided at selected points throughout their area withpairs of eyelet-stitchings 3. These stitchings are provided by firstmarking the fabric at selected points, and then stitching the eyelets onthe fabric, preferably by means of an eyelet-stitching machine devisedto accomplish the purpose.

While it is unnecessary to describe the eyelet-stitching machine in thepresent application, it may be stated that each eyelet is formed bymeans of upper and lower thread-carrying needles which have essentiallyan annular movement, as Well as a reciprocating movement, while thestitching The tufting is accomplished, in the example illustrated inFig. 2, by thrusting a long heavy needle through one of the uppereyelets of a pair, passing the needle downwardly through the mattressand outwardly through the corresponding eyelet of the lowor fabric, andthen returning the needle through the other eyelets of the pairs. The

needle carries a suitable tie a, which may be a heavy cord, or tape. Thecord is cut and the ends joined together by a knot 4. The endless loopmay then be shifted in the eye lets to bring the knot inside of themattress. The looped ends'of the tie thus engage the top and bottomfabrics B the members of the tie passing through the eyelets.

The tufting may be performed by passing the needle wholly through themattress, as illustrated; or, it may be performed by means of a curvedneedle which engages the filling in the mattress, but without passingwholly through the mattress, as is well known in the art.

The improved method enables sewed eyelets to be used economically, inlieu of metal eyelets. By the improved method, it is unnecessaryto cutopenings in the casing-fabme. upon the imperforate fabric, the selectedpoints being simply marked in advance of the eyelet-stitching operationto insure a desired arrangement, or pattern, in the tuftmg.

Theeyelet-stitching may be performed VVhat I regard as new, and desiretosecure ric to provide, at selected points through- 2 out the area ofthe fabric, pairs of stitched eyelets, thus a providing casing-top;construcing a mattress having said casing-top as 5 a part of the casing;and tufting the mattress by passing a, needle and tie c'arried therebythrough the fabric within the circle of one stitched eyelet of a pairand returning the same through the fabric within the circle 1 of theother stitched eyelet of the pair, and suitably anchoring the tie to thebody of the mattress.
